Abstract

1,090,375. Rolling. FUJI IRON & STEEL CO. Ltd. Nov. 5, 1964 [Nov. 5, 1963; May 22, 1964; July 7, 1964 (2)], No. 45196/64. Heading B3M. A method of manufacturing H-shaped bars having a large ratio of flange thickness to web thickness, or a thin web thickness, comprises cooling the flanges during a universal rolling step so as to maintain the temperature difference between the web and flanges at a minimum. A steel ingot is passed through a blooming mill 1, Fig. 5, and/or a break down mill 2, and thence to a roughing universal mill 3, where it passes through several times. The material then passes through an edging stand 4, and several times through a finishing universal mill 5, and thence to a hot-sawing machine 26, spraying apparatus 27 being provided for cooling the flanges during these operations. Apparatus 27 comprises headers 28, Figs. 6A, 6B having nozzles 29 connected thereto, the nozzles being adjustable in the vertical and horizontal directions. In a modification, adjustable nozzles 415 are provided in side guides 46, Fig. 14, or the nozzles may be non-adjustable. As the material passes through the universal rolling mill, means are provided to ensure that coolant for the rolls does not fall on to the web of the material being rolled. The universal mill comprises horizontal rolls 37, 320, and vertical rolls 323, 324, Figs. 7-9. Cooling water for the upper horizontal rolls is supplied by nozzles 318, and to the roll bearings 39 through holes 319. Covers 326, 327 having wipers 332, 333 therein, are positioned between the roll body and roll chocks 35, 36, and are connected to troughs 330, 331. Water catching shoots 335, 336 are hung by ropes 337 and rest on roll chocks 321, 322. Cooling water from the upper roll flows into the troughs, and water from the roll bearings flows down the sides of chocks 35, 36, along shoots 335, 336, on to chocks 321, 322 of the vertical roll, and therefore the water does not flow on to the web a of the workpiece.
